This type of smoke detection is typically installed in refrigerated and cold stores (assuring the temperatures do not exceed -40 degrees) and rooms, factories, or car parks that produce a high volume smoke fumes, dust particles and other fumes. Other smoke detection systems would not be suitable in these locations as the fumes would activate the alarm generating false signals.
Linear detection cable has limited states of installation such as:
- Where there is an open-circuit as it creates an infinite resistance
- In normal operating conditions, because the resistance will be identical to the end-of-line resistor
- Where fire detection installation is required as there is resistance of the linear heat cable to the short circuit.
You would use over conventional or addressable because you are less likely to receive false alarms.
